Issue with redis cluster?

dennisjohn · December 19, 2020, 1:08pm

In the task details it says the container name should be redis-contianer

I was able to execute the command that was given towards the end.

Now the task failed and shows the container name should be

Failure details
StatefulSet - Name redis-cluster container name: redis, command: ["/conf/update-node.sh", "redis-server", "/conf/redis.conf"]

Hi Dennis,

Does the Persistent volume needs to be created for each and every volume or can be done using some script ?
i did for every volume, just wanted to check if there is any other way to do it.

piVersion: v1

kind: PersistentVolume

spec:

storageClassName: manual

capacity:

storage: 1Gi

accessModes:

- ReadWriteOnce

hostPath:

path: “/redis01”

apiVersion: v1

kind: PersistentVolume

metadata:

spec:

storageClassName: manual

capacity:

storage: 1Gi

accessModes:

- ReadWriteOnce

hostPath:

apiVersion: v1

kind: PersistentVolume

dennisjohn · January 19, 2021, 12:12pm

sudheer · January 20, 2021, 6:26am

hi team, please assist here, seems there is an issue while starting the statefulset as its looking for command arguments which was passed. it says no such file or directory. Kindly look into it or check if i made some mistake

There’s a button placed to verify whatever resources are created are in good shape or not.
If you are looking for configs needed to complete the challenge, here they are -
